FASTENING DEVICE FOR CORRUGATED ROOFING AND THE LIKE.

Application filed November 14, .1923. Serial No. 674,609.

To all whom it may concern:

Be it known that I, CHARLES J. BEG-K- wrrn, a citizen of the United States of America, residing at Brooklyn, in the county 6 of Kings and State of New York, have invented certain new and useful Improve ments in Fastening Devices for Corrugated Roofing and the like, of which the following is a specification.

10 M invention relates generally to devices for fastening objects to the edge of a lateshaped support and is particularly designed to fasten corrugated metal roofin to the flat flange of an angle iron roof pur in. The

object of the invention is to produce a fastening device or cli which can be used with standard threaded lts and can be cheaply made of stock materiahsuch as heavy strap iron or light bar iron or steel. The best form of such a device embodying my invention at present known to me is illustrated in the accompanying sheet of drawings in which: a

Fig. 1 is a perspective view of the clip Fig. 2 is a cross-section through asheet of corrugated roofing and a susporting roof urlin, showing the clip an cooperating lt inoperative position. Throughout the drawings like reference characters indicate like parts. d is the sheet of corru ted roofing or siding, and c the roof pur in or other support to which it is fastened. b is a' threaded bolt assing d, an eis a washer under the head of sai bolt. f is the usual nut on the threaded end of the bolt.

0 is a clip formed of a section of standard heavy strap or light bar iron or steel per 40 forated at 9 about midway of its lengt to receive bolt 6. One end of this stra section, as h is bent at right angles to the misdlaperforated portion and the other end is bent inward at an acute angle to said middle portion, and preferably has a bifurcation or slot at its extreme end which will straddle bolt 6 when the clip is in operative position as shown in Fi 2.

The holein t e roo d is so located that 5 bolt b, assmg through 1t, extends across the lateaped support formed by the ad'acent ange of urlin c. .The clip a is then s ipped over the t readed end-of t e bolt in position such that end It overhangs the flange of purlin c and nut f is screwed down. I

The parts are so proportioned that when the bifurcated endi of the clip it rests against bolt b, or against the plate-shaped support formed by the purlinrfiange or against both and holds the perforated, middle portion of the clip at right angles to said bolt the other end k of the clip will hook over and extend along close to the other face of the. purlin flange; Thus clip (1 forms a simple, compact swiveling hook, 65 pivot-ed on the bolt, which may s ring a little under compression from nut f, ut cannot get out of position.

The clips a can be cut from a long strip, punched and slotted, at one operation in a To proper machine, and then bent cold in another operation. Consequently, they can be manufactured in quantity at small cost. They will not crack or split under excessive pressure from the nut, but afford a positive grip on the purlin, which cannot esca from this clamping action so long as t e thread on the bolt holds. It has sufiicient flexibility to be bent on the job by hammer blows to adjust it to variations in thickness of the purlin flan and one standard size of the clip will a just itself to several different sizes of purhns.

Obviously the device could be used to fasten objects, other than a sheet of oorruated roofing, to the edge of an plate. sliaped su port such as is afl'orde by the flange of t e purlin here shown as one form of such supporting structure.

Having 1. In a device for fastening objects to a plate-shaped support by means of a bolt ying across the face of said plate shaped support, a clip formed of a section of metal strap perforated at a point approximately) midway of its length to permitthe bolt to "pass through it, 'and'having one end bent at right angles to said perforated ortion and extending along one surface 0 the plateshaped support, while its other end is bent inward at an acute an le to said perforated portion, whereby sai last mentioned end j may bear on the side of the bolt when the parts are in operative position and serve as a stop to preserve sai perforated-portion in a position at right ang es to that-bolt.

escribed my invention I claim: I

2. A device such as set forth in claim 1 in which the end of the last mentioned portion of the clip is bifurcated to straddle the bolt and bears on the adjacent surface of 6 the plate-shaped support.

3. In a device for fastening metal roofing to an angle-iron purlin, the combination, with a threaded bolt passing through a hole in the roofing, extending across the face 0f 10 one flange of the angle-iron and provided with a nut on its projecting end, of a clip made of a section of metal strap perforated approximately midway of its length to permit said bolt to pass through it and having one end bent around and along the other surface of the angle iron flange While its other end is bent inward toward the bolt and bifurcated to straddle the same.
